Food safety news events classification via a hierarchical transformer model
No full textIn light of the significance of regulatory authorities and the rising demand for information disclosure, a vast amount of information on food safety news reports is readily accessible on the Internet. The extraction of such information for precise classification and provision of appropriate safety alerts based on their respective categories has emerged as a challenging problem for academic research. Given that most food safety-related events in news reports comprise lengthy text, the pre-trained language models currently employed for text analysis are generally limited in their capability to handle long documents. This paper proposes a long-text classification model utilising hierarchical Transformers. We categorise information in long documents into two distinct types: (1) multiple text chunks meeting the length constraint and (2) essential sentences within long documents, such as headings, paragraph start and end sentences, etc. Initially, our proposed model utilises the text chunks as input to the BERT model. Then, it concatenates the output of the BERT model with the important sentences from the document and use them as input to the Transformer model for feature transformation. Finally, we utilise a classifier for food safety news classification. We conducted several comparative experiments with various commonly used text classification models on a dataset constructed from publicly available information on food regulatory websites. Our proposed method outperforms existing methods, establishing itself as the leading approach in terms of performance. [Abstract copyright: © 2023 The Author(s).
Effect of Cold Spraying Parameters and Their Interaction an Hydroxyapatite Deposition
No full textCold spraying has been effectively investigated for spraying of various metals, alloys and composites. Coating of bio-ceramics like Hydroxyapatite (HAP) using thermal spraying has been investigated extensively, but there is a dearth of research related with HAP deposition using cold spraying. The relative percentage contribution of five important cold spraying parameters, their optimum combination and expected HAP particle velocity at optimum combination have been extensively discussed by the author, but no researcher reported the interactional effect of cold spraying parameters on HAP particle velocity. This paper examined the severity index of interactional effect of five important factors of cold spraying viz. gas type, gas inlet pressure, gas inlet temperature, particle size and particle temperature on HAP particle velocity. Most influential factor pairs and their influence on HAP particle velocity have been discussed with respect to various cold spraying gases viz. air, hydrogen, nitrogen and helium. In addition, CFD gas pressure and temperature distributions along the nozzle length and their mathematical validation have also been undertaken in the present paper
Surface modification of die steel materials by EDM method using tungsten powder-mixed dielectric
No full textRavi Batra. Dharma and Depressions: A Review of "The Great Depression of 1990". New York: Simon and Schuster. 1987.
No full textProfessor Ravi Batra's research and reflection have lead him
to believe that the world is headed, more or less inexorably, towards a
major depression "of the same, if not greater, severity" than the one of
the ninteen-thirties. He explains that he has written the book to warn
people and he provides a set of investment and financial tips, so that
the reader can avoid personal disaster in the "impending cataclysm".
Batra's tone is light, pleasant but totally self-assured; he "fervently
hopes that his prophecies turn out to be totally wrong" but he does not
expect this outcome. One must accept that the book is a serious effort
at scholarship and analysis and that Batra truly believes in his
underlying model and the forecasts it produces. I stress this because
there are many passages, even entire sections, in the book which, taken
by themselves, might lead one to suspect that the book is a hoax and
that the author is having fun at our expense. But, let us reject this
possibility and attempt to deal seriously with this presumably serious
book

Effect of vitamin E supplementation on immune status and alpha -tocopherol in plasma of piglets
No full textFrom day 57 of pregnancy, 12 Yorkshire gilts were given a diet without and with 5% rapeseed oil, supplemented with Se 0.1 mg and DL- alpha -tocopherol (as tocopherol acetate) 22 IU/kg feed. Colostrum (day 0) and milk (days 7, 14, 21 and 28 post partum) were sampled from gilts. At farrowing, 3 piglets from each gilt of both groups were injected with alpha -tocopherol 500 IU at birth and 1000 IU at 7 and 14 days old; 3 piglets were injected with saline and used as controls. Blood samples were taken from the newborn piglets at birth and at 7, 14, 21, 28 and 35 days old. alpha -Tocopherol concentrations and antibody titres in colostrum were significantly higher than in the milk. Plasma alpha -tocopherol concentrations and antibody titres to Keyhole limpet haemocyanin of piglets injected with tocopherol were significantly higher than controls. Tocopherol-injected piglets had significantly higher alpha -tocopherol concentrations in spleen, liver, kidney, heart, lung and hip muscle than controls..RE: 21 ref.; RN: 7782-49-2; 1406-18-4; SC: ZA; VE; BE; CA; 0I; 0N; 7D; 0V; 0DSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0926-5287&isbn=&volume=35&issue=4&spage=443&pages=443-450&date=1995&title=Reproduction%2c%20Nutrition%2c%20Development&atitle=Effect%20of%20vitamin%20E%20supplementation%20on%20immune%20status%20and%20%20alpha%20-tocopherol%20in%20plasma%20of%20piglets.&aulast=Hidiroglou&pid=%3Cauthor%3EHidiroglou%2c%20M%3bBatra%2c%20T%20R%3bFarnworth%2c%20E%20R%3bMarkham%2c%20F%3C%2Fauthor%3E%3CAN%3E19951412504%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
Effects of supplemental vitamins E and C on the immune responses of calves
No full textTwo experiments were conducted to evaluate the effects of oral supplementation of vitamin C and vitamin E (alpha-tocopherol), alone and in combination, on immune responses of calves. In Experiment 1, 18 Holstein newborn female calves were supplemented with 0, 1, and 2 g/d of vitamin C from birth to 6 wk of age. Concentrations of ascorbic acid in blood plasma were significantly higher for supplemented calves than for control calves. No significant differences among treatments occurred in the concentrations of IgG1, IgG2, and titer to keyhole limpet hemocyanin. In Experiment 2, effects of oral supplementation of vitamins E and C on immune responses were studied using 18 Holstein female calves. Concentrations of alpha-tocopherol in blood plasma were significantly higher for supplemented than for control calves. The concentrations increased from birth to wk 1, and then very little change occurred from wk 1 to 6. Differences among treatments in the concentrations of IgG1, IgG2, IgM, and titer to keyhole limpet hemocyanin were not significant; however, concentrations of IgM in calves supplemented with vitamins E and C generally tended to be higher than those of control calves. Antibodies to keyhole limpet hemocyanin were higher at 6 wk than at 4 wk of age.LR: 20031114; PUBM: Print; JID: 2985126R; 0 (Antibodies); 0 (Antigens); 0 (Immunoglobulin G); 0 (Immunoglobulin M); 0 (keyhole-limpet hemocyanin); 1406-18-4 (Vitamin E); 50-81-7 (Ascorbic Acid); 9013-72-3 (Hemocyanin); ppublishSource type: Electronic(1
